Weather

2. perceptible natural movement of the air, especially in the form of a current of air blowing from a particular direction.
7. the occurrence of a natural electrical discharge of very short duration and high voltage
8. Chart: A thermodynamic diagram with temperature as abscissa and pressure as ordinate.
9. Transport of an atmospheric property solely by the mass motion of the atmosphere.
10. A thermodynamic change of state of a system in which there is no transfer of heat or mass (i.e. compression results in warming, expansion in cooling).
12. Transport of an atmospheric property solely by the mass motion of the atmosphere.
13. stream. a narrow variable band of very strong predominantly westerly air currents.
14. Wind An upslope wind is usually applied only when the wind is blowing up hill or mountain as the result of local surface heating, and apart from the effects of the larger scale circulation.
15. a sudden brief increase in wind speed

1. Instrument designed to measure the speed of the wind.
3. detached, individual, cauliflower-shaped clouds usually spotted in fair weather conditions
4. clouds covering a large part of the sky
5. a cloud that touches the ground
6. A thermodynamic change of state of a system in which there is no transfer of heat or mass
11. the turning of a south or southwest surface wind with time to a more east or southeasterly direction
